Description

一种按键结构及应用其的键盘 技术领域
本实用新型属于计算机周边设备领域，尤其涉及输入设备键盘。
 背景技术
计算机键盘目前已经普遍适用到各个领域，人们在追求简便价廉的同时也逐渐开始追求使用手感，现有技术中有一种机械键盘，比较长的按键诸如空格键、上档键等按键，在使用过程中为了防止按键下压过程中发生不平衡状态，通常使用平衡杆的结构，成本比较高，需要使用将按键开关置于中央，而两边使用两个支架，每个支架内设有可上下活动的平衡键，该平衡键下端连接平衡杆的端部，该平衡键的上端连接键帽，键帽内设有十字凹槽三个，分别与按键开关、两个平衡键相连接，当键帽任意位置受压向下运行时，平衡键在平衡杆的联动作用下保持相同的下压动作，故此能够使按键开关正常导通。但上述现有技术的存在一定不足之处，第一，平衡杆安装置于开孔铁板下方，这样给安装带来众多不便，提高了人工工作成本；第二，支架和平衡键的设计也增加了组件开模费用，也提高了成本。
 技术问题
本实用新型的目的在于提供一种按键结构，旨在解决现有技术中生产成本较高的问题。
 技术解决方案
本实用新型是这样实现的，一种按键结构，其包括键帽，开关，平衡杆，至少两个支架，所述支架呈开口朝上的腔体，所述支架上方一端设有可支撑所述平衡杆的轴孔，所述平衡杆呈“U”型，所述键帽内设有可与所述平衡杆端部活动连接的卡榫，所述卡榫置于所述支架的空腔内，所述开关置于两个所述支架之间，所述开关上端按钮与所述键帽内部配合连接。
优选地，所述卡榫侧表面上下分布两个凸起，所述平衡杆端部卡于所述凸起之间。
优选地，所述支架前后两个垂直表面设有用于卡住键盘铁板开孔边缘的卡扣。
优选地，所述支架其中一个垂直面的卡扣呈弹性卡扣。
优选地，所述支架呈纵向左右对称设计，所述轴孔左右两边各分布一个。
优选地，所述平衡杆“U”字型横向连接部向外部凸出。
 有益效果
依借上述技术方案，本实用新型所提供的按键结构相对于现有技术具有以下有益效果，空腔支架的设计减少了现有技术中平衡键的设置，故此将节约了成本，同时，现有技术中，平衡杆是安置在支架的下方，而本实用新型是在所述支架上方，在生产装配过程中极大的简化了工作量，提高了工作效率。
本实用新型还提供一种键盘，可以解决超长按键安装不便的问题。
所述键盘包括底板，上盖，PCB板，开孔铁板，其特征在于，所述键盘使用上述技术方案所述的按键结构，所述支架通过其卡扣卡入所述开孔铁板的开孔边缘，所述开关底部焊接在所述PCB板上，所述平衡杆折弯处置入所述支架的轴孔中，所述平衡杆端部置于所述键帽卡榫的凸起之间，所述上盖置于所述支架上方并进行固定连接。
生产过程中，将焊接后开关的PCB板置入所述底板内后，套装上所述开孔铁板，然后安装所述支架，再将平衡杆安装在所述支架上方，最后装配所述键帽，这样的生产方式简单方便。

 本发明的实施方式
为了使本实用新型的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本实用新型进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本实用新型，并不用于限定本实用新型。
参照图1-6所示，本实用新型实施例提供一种按键结构，其包括键帽1，开关4，平衡杆2，至少两个支架3，所述支架3呈开口朝上的腔体，所述支架3上方一端设有可支撑所述平衡杆的轴孔31，所述平衡杆2呈“U”型，所述键帽1内设有可与所述平衡杆2端部活动连接的卡榫11，所述卡榫11置于所述支架3的空腔内，所述开关4置于两个所述支架3之间，所述开关4上端按钮与所述键帽1内部配合连接，所述开关4下端与PCB板6连接，依借上述技术方案组装的按键结构，当键帽1下压时，所述键帽1向下施加的力通过所述卡榫11传递给所述平衡杆2，而所述平衡杆2以所述轴孔31为支点联动所述平衡杆2另一端的卡榫11，致使所述键帽1保持水平下压对所述开关4施力，本实用新型所提供的按键结构相对于现有技术具有以下有益效果，空腔支架的设计减少了现有技术中平衡键的设置，故此将节约了成本，同时，现有技术中，平衡杆是安置在支架的下方，而本实用新型是在所述支架3上方，在生产装配过程中极大的简化了工作量，提高了工作效率。
所述卡榫11侧表面上下分布两个凸起110，所述平衡杆2端部卡于所述凸起110之间，所述键帽1上下运用过程中，所述平衡杆2的端部会在所述凸起110之间滑动，同时还以两个凸起110为支点达到促使联动的作用。
进一步地，所述支架3前后两个垂直表面设有用于卡住键盘铁板5开孔边缘的卡扣32，所述卡扣32是为了固定所述支架3。
更进一步地，所述支架3其中一个垂直面的卡扣33呈弹性卡扣，方便将所述支架3卡入到键盘开孔铁板5的开孔51中。
所述支架3呈纵向左右对称设计，所述轴孔31左右两边各分布一个，虽然在具体装配过程中，所述平衡杆2的转弯处只需与所述支架3上的一个轴孔31配装即可，但所述支架3体积较小，如果只设计一个轴孔31的话就需要用两个模具生产，成本提升，另外在装配过程中需要分左右支架，也会给装配工作带来效率的降低，所以设计为对称的双轴孔，可以既节省了开模的费用，而且还能提高生产效率，一举两得。
所述平衡杆2“U”字型横向连接部向外部凸出，以绕开所述开关4的位置。
本实用新型还提供一种键盘，可以解决超长按键安装不便的问题。
所述键盘包括底板（未示出），上盖（未示出），PCB板6，开孔铁板5，所述键盘使用上述技术方案所述的按键结构，所述支架3通过其卡扣32、33卡入所述开孔铁板5的开孔51边缘，所述开关4底部焊接在所述PCB板6上，所述平衡杆2折弯处置入所述支架3的轴孔31中，所述平衡杆2端部置于所述键帽1卡榫11的凸起110之间，所述上盖置于所述支架3上方并进行固定连接。
生产过程中，将焊接开关4的PCB板6置入所述底板内后，套装上所述开孔铁板5，然后安装所述支架3，再将平衡杆2安装在所述支架3上方，最后装配所述键帽1，这样的生产方式简单方便。
以上所述仅为本实用新型的较佳实施例而已，并不用以限制本实用新型，凡在本实用新型的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本实用新型的保护范围之内。
